The invention relates to erossties for railroad tracks, and hasparticular reference to improvements in cross ties forlaying tracks inmines for room work and heading development, and also for lightindustrial tracks.

The invention has for its principal object the provision of a cross tiethat may be used for laying temporary tracksand dispensing with thenecessity for fish plates, bolts, spikes and wooden ties and that'willalso adequately bond the rails used in room work and heading developmentin coal mines and thus make it possible to use the track for the returncircuit'of electrically operated mining' machines and gathering motors,thus making itpossible to operate these utilities by a single cable anddispense with the'danger ofmine fires where double cables are.

used and when'they b ecome shorted. A further object of the inventionis' the provision of across tie having means for clamping the railroadrails thereto comprising fixed clampingm'embers engaging the tie, andwedge meansfor cooperating with the fixed clamping members to engage therails with the tie. i

A further object of .6 the invention is the provision of a cross tie forrailroad tracks formed of channel beams having their ends returned andriveted or otherwise'secured together and the extremities of the tiessnacedfrom the intermediate portions thereof to receive edges to coactwith secured clamping means for the railroad rails to hold the rails inengagement with the ties.

' A further object of the invention is the,

provision in a railroad cross tie of the type heretofore referred tohaving clamping means secured thereto and another clampingmeansadjustably mounted thereon andpro vided with separate clamping members'to engage the meeting ends of railroad rails to secure them together tothe exclusion of fish plates and bolts and that will so closely engagethe rail' ends' as to form an electric bond for the meeting ends ofrails and thus eliminate the necessity of bonding the ends of the rails.

The invention will be described in detail hereinafter and will be foundillustrated in the accompanying drawings in which Figure 1 is a top planview of one of the improved cross ties of a type to secure one oftherails intermediate of its ends at one end of the tie and to connect theabutting ends of meeting rails at the other end of the and shownfragmentarily,

In the drawings similar reference characte'rs will beused to designatecorresponding. parts thro'ughout the several views;

The improved railroad rail is formed preferably of channel beams havingthejflanges extending downwardly so that-when laid'on the floor of amine or in other position the flanges will prevent creepingof the same.

The tie is, designated 1 and has its ends re turned as shown at 2 andthe returned portions secured'by means of rivets 3 or in any othersuitable manner. The ends of the re-' turned portions are then formedwith upwardly and inwardly inclined portions 4 and the extremitiesbformed on planes substan tially parallel with the intermediate portionsof the tie 1. l j l In the form of tie selected for illustration, invFigures 1 and 2, one end of the tie is designed to be connected toarail A, intermediate of'its ends, while the other end of the tie isdesignedto connect the meeting ends of railroad rails'designated B and Crespectively. The. rail A is secured in position on the tie by means ofa clamp member 6 that is preferably formed of channel And Web of therail and act as a brace therefor.

The clamping means for the meeting ends of the railroad rails B and C,at the other end of the tie 1 are two elongated U-shaped membersdesignated 13 and 14, the clamping member 13 having a tongue 15extending on the same plane with the base 16 of the member and adaptedto be secured to the tie by rivets 1? or other suitable fastening means,while the clamping member 141 has a tongue 18 extending substantiallyperpendicularly to the base 19, and said clamping member 14 is slidablymounted on thebase and adjustably secured thereto by means of a rivet 21engaging in slot 20. As the tongues 15 and 13 in the clamping members 13and 14, respectively, are formed from the metal of the clamp by cuttingthe part bent upwardly and back on the bases 16'and 19, respectively, itwill be apparent that the clamping members 13 and 1.4-. are providedwith engaging members 22 and 23 respectively, that are spaced from oneanother on each of the clamping members so that separate engagingmembers for the rails B and C are provided and provision made forclosely clamping the rail and bonding means for connecting the rails aretherefore provided that the rails may be used for one of the circuit:connections between a mining machine located in the room or drift intowhich the track may be laid or the motor comprising the motivepower forthe mine cars The means for holding the rails B and C clamped betweenthe members 13 and 1 1 comprises a wedge 24: having an inclined outerface 25 to engageincl-ined portion 4,

and adapted to engage tongue 18 on clamp member 14 and hold it inclamping relationship with the railroad rails. j

While the tie illustrated in Figures 1 and 2 is designed, as heretoforestated, to connect at one end a rail intermediate of its ends, and theother end provided with means for clamping the meeting ends of tworails, it will be apparent that other ties may be provided having bothof their ends provided with means for engaging rails intermediate oftheir ends, it being apparent that as the ties are reversible the tieillustrated in Figures 1 and 2 maybe utilized for connecting abuttingends of rails at either side of-the track by simply reversing the tie.

, In Figures 9 and 1 0 are shown a means for clamping balled rails inwhich 31 indicates the tie, 32 a rail clamp secured to the tie by meansof rivets 33 or other suitable fastening means, and having a plate 34over lying the clamp 32 and secured by the rivets 33, said plate 34:extending beyond the clamping end 35 of the clamp 32 as shown at 36 toengage the ball of the rail B as illus trated, a wedge 37 being employedto clamp the rail in position.

What is claimed is: v 1. A cross tie, comprising a beam' having returnedportions adjacent to the ends therec of, securing means connecting thebeam and said returned portions, the extremities of the beam spaced fromthe intermediate portion thereof and adapted to receive clamping wedgesto fasten the outer portions of railroad rails, and clips secured to thebeam to engage inner portions of rail bases,

2. A cross tie, comprising a beam having a returned portion adjacent toan end there-- of, securing means connecting the beam and said returnedportion, the extremity of the beam spaced from the intermediate portionthereof and adapted to receive a {clamping wedge to fasten the outerportion of rail road rail, a clip slidably mounted on the beam to engagethe-base of the rail and on gageable by said wedge, and means on thebeam to engage the outer side of the base.

3. A cross tie, comprising a beam having returned portion adjacent to anend there of, the extremity of the beam spaced from the intermediateportion thereof, and adapted to receive a clamping wedge to fasten theouter portion of a railroad rail, a clip slid ably mounted on the beamto engage the base of the rail and e-ngageable by said wedge,-a studsecured to said clip and slidable in a slot in the beam, and means onthe beam to engage the other side of the rail base.

4. Securing means for the meeting ends of railroad rails comprisin'gaclamping memher having a base portion, and returned portions on saidbase spaced from one another to separately engage the adjacent ends ofmeeting rails. I J r In testimony whereof we afiix our signa tures. 1
